ALARM ATTACHMENT For; DRIP-FANS.

Specification of Letters Patent.

Patented Jan. 9, 1917.

Application filed April 20, 1916. Serial No. 92,500.

To all whom it"may concern:

Be it known that I, HARRYBUoKs, a citi Zen of the United States of America, and resident of Somerville, in the county of Middlesex and. State of Massachusetts, have invented certain new and useful Improvements in Alarm Attachments for Drip-Pans, of which the following is a specification.

This invention relates to signals and particularly to means for sounding an alarm when water in a drip panof arefrigerator has reached a predetermined height and prior to the time it overflows the receptacle constituting the drip pan.

An object of this invention is to provide novel means for mounting a float so that it may rise and fall in the said receptacle following the level of the water in the drip pan, means being provided whereby the said float controls an alarm or trip mechanism controlling the alarm so that when said mechanism is tripped, the alarm will be sounded so that the attention of the occupant of the place where the refrigerator is stationed may be directed to the fact that the water in the drip pan has reached a predetermined level.

A further object of this invention is to provide novel means whereby the mechanism for creating the alarm may be applied to or removed from the receptacle, means being further provided for insuring the re-- tention of the said device on the wall of the said receptacle.

l/Vith the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement .and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification wherein like characters denote corresponding parts in the several views, and in which- Figure 1 illustrates a sectional view of a fragment of a refrigerator with the drip pan shown in section and the alarm mechanism in elevation applied thereto; Fig. 2 illustrates a front view of the alarm mechanism omitting the float; Fig. 3 illustrates a view in elevation of the rear of the alarm mechanism; Fig. 4 illustrates a plan view of a blank from which the alarm carrying clamp is formed.

In these drawings 6 denotes the refrigerator, 7 the drip pan which refrigerator and drip pan may be of any ordinary construction and will not, therefore, be described in detail.

The alarm mechanism comprises a clamping member 8 adapted to embrace the edge of a drip pan, the said clamping member being of such construction as to frictionally engage the outer and inner walls of the drip pan to prevent dislodgment of the signaling mechanism. The clamp is formed from the blank shown in Fig. 2 and is preferably bent on the lines 9 and 10 to form the inner jaws 11 and 12 and outer jaws 13 and 14, the ends of which preferably contact the wall of the pan. The blank is cut to form a tongue 15 which may be bent to create a handle and another tongue 16 is formed when the blank is cut, the said tongue 16 being bent upwardly to form a lug constituting a bracket for a purpose to be presently explained. The tongue 16 has an aperture 17 and this aperture is created to receive a screw 18 by which the bell'20 is secured to the clamp. The bell body is adapted to contain a spring motor (not shown) which will operate a clapper to strike the bell 21 and as these parts are of ordinary construction, the interior mechanism of the bell willnot be disclosed. The bell has a trip or motor releasing device-22 which upon being pushed inwardly operates to release the motor and drive the clapper and this releasing device is normally pressed outwardly in which position the motor is at rest.

When the releasing device is pushed inwardly, as stated, the bell will ring and so in order to sound an alarm when water in the drip pan 7 has reached a predetermined level, a float 23 is provided with an arm 24,

the said arm being pivotally mounted in such relation to the releasing device 22 as to engage said releasing device when the float rises to a predetermined level and the engagement of the arm with the releasing device results in the releasing device being actuated and, thereafter the alarm is sounded.

In order to pivotally mount the float arm, the inner end thereof is bent at an angle as shown at 25 and pivoted in a loop 26 formed by the tongue 29 which is integral with the plate 9. One end of the blank 7 is cut to form a tongue A and said tongue is provided with furcations 30, which are bent outwardly and upwardly to embrace and form guides for the float arm to insure the engagement of the float arm and the releasing means of the bell.

As shown in the drawings, the body or clamp carries all of the mechanism necessary for operating the alarm as well as the alarm itself and therefore the alarm mechanism may be readily removed from the receptacle when it is to be emptied and may be reapplied thereto before returning the receptacle to position to receive the drip pings from the refrigerator.

The device is of simple and comparatively inexpensive construction and durable.

I claim:

In an alarm attachment for drip pans, a clamp comprising a plate bent on itself to form spring jaws, a handle integral with one of said jaws, a bracket integral with the other of said jaws, said bracket having a slot therein forming a guide, tongues integral with the last mentioned clamp, one of said tongues having a hole therein and constituting a bracket, a bell attached to said bracket, the other of said tongues being shaped to form a bearing, an arm having an angular extension supported in the bearing, the main portion of the arm being movable in the slot of the first mentioned bracket and in position to operate the bell.

In testimony whereof, I affix my signature in the presence of two witnesses.
